WATERPROOFING AND PRESERVATIVE COMPOUND.

SPECIFICATION forming part of Letters Patent No. 253,369, dated February '7, 1882.

' Application filed December 8, 1881. (No specimens To all whom it may concern Be it-known that I, JAMEs E. GILLEsPIE, of Warwick, in the county of Orange and State of New York, have invented a certain new and Improved Waterproofing and Preserv'ative Compound, of which the following is a specification.

My improved compound is applicable to fabrics made of fibrous material by felting, weaving, or otherwise, to leather and to wood, or

other materials.

The invention consists in a waterproofing and preservative compound composed of ozocerite or mineral wax and a siecative vegetable oilsuch,forinstanoe,aslinseed-oil. The proportions which 1 have used successfully are one (1) part, by weight, of ozocerite or mineral wax, and two (2) parts, by weight, of linseed-oil, cotton-seed oil, or any other suitable siccative vegetable oil. These proportions may, however, be varied for treating different substances under varying conditions.

The compound is made by placing the ozocerite and oil together in a suitable vessel heated to a temperature sufficient to melt the ozocerite and enable it to be incorporated with the oil, which is about one hundred and eighty degrees (180 Fahrenheit, or upward.

The fabric or other materiatto be waterproofed and preserved is treated in the following manner: The compound f ozooerite and oil heated sufficiently to render it fluid is applied to the surface of the fabric or material with a brush or by any other means, and the fabric or material is then placed in a chamber or other place heated to a temperature of from one hundred and fifty degrees (150 to two hundred and fifty degrees (250) Fahrenheit,

and allowed to remain therein for a very short time to allow the ozocerite and oil to strike into and thoroughly penetrate the fabric or material. This application of ozocerite and oil and the subsequent heating may be repeated when necessary, and as often as is desirable.

The ozocerite and oil may be applied with great advantage to seamless woven hose.

I do not here claim the use of ozocerite alone as a waterproofing substance, as this may form the substance of a future application for Letters Patent.

NVhat I claim as my invention, and desire to secure by Letters Patent, is-

1. A waterproofing and preservative compound composed of ozocerite or mineral wax and a siccative vegetable oil, substantially as herein described.

2. A waterproofing and iweservative compound composed of ozocerite or mineral wax and linseed -oil, substantially as herein described.
